CONCORD - N.H.'s Supreme Court has rejected an appeal from a former gunpowder plant owner imprisoned over a deadly 2010 explosion.
Craig Sanborn of Maidstone, Vermont, was convicted in 2013 of two counts of manslaughter and two counts of negligent homicide. He was sentenced to 10 to 20 years in prison on the manslaughter counts.
The court on Friday rejected challenges to jury selection, evidence, the verdict, and sentence.
Sanborn's lawyer argued the conviction should be overturned because there were many potential causes for the blast. The state said Sanborn's instructions to workers to load the grinding machines while they operated created the excessive gunpowder dust cloud that ignited and triggered subsequent explosions of buckets of gunpowder.
Two workers were killed at the Black Mag gunpowder plant in Colebrook.
